* 5V 1 Channel Relay Module Low level for DIY project

 * The module uses genuine quality relay, normally open interfaces

 * Using SMD optocoupler isolation, driving ability, stable performance

 * The module can be high or low by a jumper setting trigger

 * Fault-tolerant design, even if the control line is broken, the relay will not operate

 * The power indicator (green), the relay status indicator (red)

 * The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient

Specification:

 * Maximum load: AC 250V/10A, DC 30V/10A

 * Trigger current: 5mA

 * Working voltage: 5V

 * Module size: 50 x 26 x 18.5mm (L x W x H)

 * Four mounting bolts holes, diameter 3.1mm

 * DC+: positive power supply (VCC)

 * DC-: negative power supply (GND)

 * IN: can be high or low level control relay

 * NO: normally open relay interface

 * COM: Common Interface Relays

 * NC: normally closed relay interface
